LDAP Authentication integration provides the ability to authenticate your users directly against an LDAP service such as OpenLDAP or Active Directory.
LDAP Users are not imported into Form.io as Resources and exist only externally in LDAP. They still get assigned Form.io roles and can have ownership over forms and submissions.
Set up LDAP Settings
To being using LDAP Authentication, get the Bind DN and Password for your LDAP service. These are used to find the user account’s DN in LDAP. Enter your Server URL, Bind DN, Bind Password, Search Base and Search Filter into the LDAP settings.
By default Form.io uses email addresses to login in users so using the email attribute in the search filter is recommended unless you change the User Login form to match the search filter. For example
Add LDAP Login Action to Form
Once you have LDAP set up, add an action to your User Login Form for the “LDAP Login” action.
Select the form field that represents your username in LDAP. It must be a string or email field.
Select the form field that represents your password in LDAP. It must be a password field.
If you choose the Passthrough option, any failures except for a failure to Bind the user account, will be ignored and the login information will be passed to the next form action. This allows using both LDAP and the Form.io Login action on the same form.
Next map any LDAP properties to user roles. Select the property, the matching value and the role to assign it true. Leave LDAP Property and Value blank to assign the role to all LDAP accounts.
- LDAP Property: group
- Value: Admins
- Role: Admin
Would assign the Admin role to any members of the Admins group.
The user’s DN is also mapped to the list of properties so if the DN is
dn=myname,ou=admins,dc=example,dc=org you can do:
- LDAP Property: ou
- Value: admins
- Role: Admin
